I'm designing a 5A MPPT charger from a solar panel VOC=23V VMP=19.8V. The Battery pack is a 12.8V 4S4P LifePo4, the max charge voltage is 14.4V.
How do i set the FB pin so that the max charge voltage is 14.4V ? It's not very clear at all in the datasheet ?
Hello,
Table 1 in the datasheet shows the FB servo values for various modes of operation. For your selected mode, refer to those values for Vfb. You would then calculate a voltage divider such that the…

You can just use a calculator like this one: https://ohmslawcalculator.com/voltage-divider-calculator
